         invoices with respect to applicable expenses not exceeding $25,000 that
         are to be (and are permitted to be) paid with the proceeds of any
         Tranche B Borrowing if the Borrower attaches a certificate of a
         Financial Officer to the effect that such expenses have been or will be
         properly paid with the proceeds of Tranche B Loans in accordance with
         Section 5.10 of the Common Agreement and Section 5.02 hereof;

                  (ii) the date of such Borrowing, which shall be a
         Business Day;

                  (iii) whether such Borrowing is to be a LIBOR Borrowing or an
         ABR Borrowing (and, if such Borrowing is to be a LIBOR Borrowing, the
         duration of the initial Interest Period applicable thereto);

                  (iv) the Class of such Borrowing; and

                  (v) if any proceeds of such Borrowing are to be advanced in
         cash to the Borrower, the location and number of the Borrower's account
         to which funds are to be disbursed, which shall comply with the
         applicable requirements of the Funding Agreement and the Collateral
         Agency Agreement.

If no election as to the Type of Borrowing is specified, then the requested
Borrowing shall be an ABR Borrowing. Promptly following receipt of a Borrowing
Request in accordance with this Section, the Administrative Agent shall advise
each Lender of the details thereof and of the amount of such Lender's Loan to be
made as part of the requested Borrowing.

                  (b) Notwithstanding anything to the contrary contained in this
Agreement, the Administrative Agent shall, at the request of Cisco so long as
Cisco Lenders are the only Lenders with Tranche A Commitments hereunder, cause
Tranche A Loans to be advanced by the Lenders for and on behalf of the Borrower
whether or not (i) any Borrowing Request is given in accordance with Section
2.03(a), (ii) any of the conditions precedent set forth in Article IV hereof are
satisfied, (iii) any Default exists, or (iv) any other fact or circumstance
exists, if Cisco shall have given five Business Days' prior written notice to
the Administrative Agent and the Borrower of Cisco's desire to cause the Lenders
to make such Loans and all proceeds of



                                       16
<PAGE>

such Loans are used to pay the Purchase Price of Qualifying Purchases under the
Cisco Supply Contract that have not been disputed and that have not been paid
when due. All Loans advanced pursuant to this Section 2.03(b) shall be Tranche A
Loans and shall be initially advanced as LIBOR Borrowings with a three month
Interest Period or, if the maximum number of Interest Periods for LIBOR
Borrowings is already then in effect, as ABR Borrowings (but after such
advancement, such Borrowings may be converted or continued in accordance with
Section 2.05 of this Agreement). For the purposes of this Section 2.03(b), if a
Lender that is not a Cisco Lender holds a Tranche A Commitment that, when
funded, would result in a Cisco Loan, such Lender shall be deemed to be a Cisco
Lender.

                  SECTION 2.04. FUNDING OF BORROWINGS. (a) Each Lender shall
make each Loan to be made by it hereunder on the proposed date thereof by wire
transfer of immediately available funds by 12:00 noon, New York City time, to
the account of the Funding Agent most recently designated for such purpose by
notice to the Lenders in accordance with the Funding Agreement, or as otherwise
provided in the Funding Agreement. The proceeds of the Loans shall be made
available by the Funding Agent as provided in the Funding Agreement.

                  (b) Unless the Funding Agent shall have received notice from a
Lender prior to the proposed date of any Borrowing that such Lender will not
make available to the Funding Agent such Lender's share of such Borrowing, the
Funding Agent may assume that such Lender has made such share available on such
date in accordance with paragraph (a) of this Section and may, in reliance upon
such assumption, make available to or for the account of the Borrower a
corresponding amount as provided in the Funding Agreement. In such event, if a
Lender has not in fact made its share of the applicable Borrowing available to
the Funding Agent, then the applicable Lender and the Borrower severally agree
to pay to the Funding Agent forthwith on demand such corresponding amount with
interest thereon, for each day from and including the date such amount is made
available to but excluding the date of payment to the Funding Agent, at (i) in
the case of such Lender, the greater of the Federal Funds Effective Rate and a
rate determined by the Funding Agent in accordance with banking industry rules
on interbank compensation or (ii) in the case of the Borrower, the interest rate
applicable to ABR Loans. If such Lender pays such amount to the Funding Agent,
then such amount shall constitute such Lender's Loan included in such Borrowing.

                  SECTION 2.05. INTEREST ELECTIONS. (a) Each Borrowing initially
shall be of the Type specified in the applicable Borrowing Request. Thereafter,
the Borrower may elect to convert such Borrowing to a different Type or to
continue such Borrowing, as provided in this Section. The Borrower may elect
different options with respect to different portions of the affected Borrowing,
in which case each such portion shall be allocated ratably among the Lenders
holding the Loans comprising such Borrowing, and the Loans comprising each such
portion shall be considered a separate Borrowing.

                  (b) To make an election pursuant to this Section, the Borrower
shall notify the Administrative Agent of such election by telephone by the time
that a Borrowing Request would be required under Section 2.03 if the Borrower
were requesting a Borrowing of the Type resulting from such election to be made
on the effective date of such election. Each such telephonic Interest Election
Request shall be irrevocable and shall be confirmed promptly by hand delivery or
telecopy to the Administrative Agent of a written Interest Election Request in a
form reasonably satisfactory to the Administrative Agent and signed by the
Borrower.

                  (c) Each telephonic and written Interest Election Request
shall specify the following information in compliance with Section 2.02:

                  (i) the Borrowing to which such Interest Election Request
         applies and, if different options are being elected with respect to
         different portions thereof, the portions thereof to be allocated to
         each resulting Borrowing;

                  (ii) the effective date of the election made pursuant to such
         Interest Election Request, which shall be a Business Day;

                  (iii) whether the resulting Borrowing is to be a
         LIBOR Borrowing or an ABR Borrowing; and

                  (iv) in the case of a LIBOR Borrowing, the duration
         of the Interest Period applicable thereto.

                  (d) Promptly following receipt of an Interest Election
Request, the Administrative Agent shall advise each Lender of the details
thereof and of such Lender's portion of each resulting Borrowing.

                  (e)  If the Borrower fails to deliver a timely
Interest Election Request with respect to a LIBOR Borrowing



                                       18
<PAGE>

prior to the end of the Interest Period applicable thereto, then, unless such
Borrowing is repaid as provided herein, at the end of such Interest Period such
Borrowing shall be continued as a LIBOR Borrowing with an Interest Period of
three months' duration (or converted to an ABR Borrowing, if the end of such
Interest Period occurs less than three months prior to the Maturity Date).
Notwithstanding any contrary provision hereof, if an Event of Default has
occurred and is continuing and the Administrative Agent, at the request of the
Required Lenders, so notifies the Borrower, then, so long as an Event of Default
is continuing (i) no outstanding Borrowing may be converted to or continued as a
LIBOR Borrowing and (ii) unless repaid, each LIBOR Borrowing shall be converted
to an ABR Borrowing at the end of the Interest Period applicable thereto.

                  SECTION 2.06. TERMINATION AND REDUCTION OF COMMITMENTS.
Commitments shall be terminated or reduced as provided in and subject to the
requirements of Sections 2.02 and 2.03 of the Common Agreement.

                  SECTION 2.07. REPAYMENT OF LOANS; EVIDENCE OF DEBT. (a) The
Borrower hereby unconditionally promises to pay to the Administrative Agent for
the account of each Lender the then unpaid principal amount of each Loan of such
Lender as provided in Section 2.08.

                  (b) The Administrative Agent shall maintain accounts in which
it shall record (i) the amount of each Loan made hereunder, the Lender making
such Loan, the Class and Type thereof and the Interest Period applicable
thereto, (ii) the amount of any principal or interest due and payable or to
become due and payable from the Borrower to each Lender hereunder and (iii) the
amount of any sum received by the Administrative Agent hereunder for the account
of the Lenders and each Lender's share thereof.

                  (c) The entries made in the accounts maintained pursuant to
paragraph (b) of this Section shall be PRIMA FACIE evidence of the existence and
amounts of the obligations recorded therein; PROVIDED that the failure of the
Administrative Agent to maintain such accounts or any error therein shall not in
any manner affect the obligation of the Borrower to repay the Loans in
accordance with the terms of this Agreement.

                  (d) The Borrower shall prepare, execute and deliver to each
Lender a promissory note payable to such Lender and its registered assigns and
in a form approved by the Administrative Agent. The Loans shall at all times
(including after assignment pursuant to Section 9.04) be



                                       19
<PAGE>

represented by one or more promissory notes in such form payable to the payee
named therein and its registered assigns.

                  SECTION 2.08. AMORTIZATION OF LOANS. (a) Subject to adjustment
pursuant to paragraph (c) of this Section, the Borrower shall repay Borrowings
on each date set forth below in an aggregate amount equal to the percentage set
forth opposite such date multiplied by an amount equal to the sum of all Loans
made hereunder (whether or not previously repaid):

                        DATE                           PERCENTAGE
                        ----                           ----------
                    June 30, 2004                          5%
                  December 31, 2004                        5%
                    June 30, 2005                         10%
                  December 31, 2005                       10%
                    June 30, 2006                         10%
                  December 31, 2006                       15%
                    June 30, 2007                         15%
                  December 31, 2007                       15%
                    June 30, 2008                         15%

                  (b) To the extent not previously paid, all Loans shall be due
and payable on the Maturity Date.

                  (c) Any prepayment of a Borrowing made pursuant to paragraph
(a) of Section 2.03 of the Common Agreement shall be applied to reduce the
subsequent scheduled repayments of the Borrowings to be made pursuant to this
Section ratably. Any other prepayment of a Borrowing shall be applied to reduce
the subsequent scheduled repayments of the Borrowings to be made pursuant to
this Section in reverse chronological order; PROVIDED that prepayments of
Borrowings as a result of any Agency Capital Market Transaction arranged by
Cisco shall be applied to reduce the subsequent scheduled repayments of the
Borrowings to be made pursuant to this Section in such manner and order so that,
immediately after giving effect thereto, the scheduled repayments of the
Borrowings to be made pursuant to this Section, together with the scheduled
repayments of the principal in respect of the Indebtedness incurred pursuant to
such Agency Capital Market Transaction that resulted in such prepayment,
combined, will be the same as (or at any time not greater than) the remaining
scheduled repayments of the Borrowings to be made pursuant to this Section
immediately prior to such prepayment.

<PAGE>

                  (d) Prior to any repayment of any Borrowings hereunder, the
Borrower shall select the Borrowing or Borrowings to be repaid and shall notify
the Administrative Agent by telephone (confirmed by telecopy) of such selection
not later than 2:00 p.m., New York City time, three Business Days before the
scheduled date of such repayment; PROVIDED (i) that the Borrower shall select
Borrowings to be repaid such that each Lender shall receive its pro rata share
of such repayment as provided in Section 2.16 and (ii) such selection shall be
made in accordance with Section 2.03 of the Common Agreement. Each repayment of
a Borrowing shall be applied ratably to the Loans included in the repaid
Borrowing. Repayments of Borrowings shall be accompanied by the payment of
accrued interest on the amount thereof.

                  SECTION 2.09. PREPAYMENT OF LOANS. The Borrowings shall be
subject to optional and mandatory prepayment as set forth in Section 2.03 of the
Common Agreement.

                  SECTION 2.10. FEES. (a) The Borrower agrees to pay to the
Administrative Agent for the account of each Lender a commitment fee, which
shall accrue at a rate per annum equal to 1.50% on the daily aggregate amount of
the Commitments of such Lender (or, during the period from and including the
Closing Date to but excluding the Effective Date, on the excess of the daily
aggregate amount of the Commitments of such Lender over the corresponding daily
aggregate principal amount of any outstanding Indebtedness owed by any Loan
Party to such Lender to finance the purchase of equipment or services from
Cisco) during the period from and including the Closing Date to but excluding
the date on which the Commitments terminate (including pursuant to Section 2.02
of the Common Agreement). Accrued commitment fees shall be payable in arrears on
the last day of March, June, September and December of each year and on the date
on which the Commitments terminate, commencing on the first such date to occur
after the Closing Date. All commitment fees shall be computed on the basis of a
year of 360 days and shall be payable for the actual number of days elapsed
(including the first day but excluding the last day).

                  (b) The Borrower agrees to pay to Cisco, for its own account,
fees in the amounts and at the times separately agreed.

                  (c) The Borrower agrees to pay to the Administrative Agent,
for its own account, fees in the amounts and at the times separately agreed.




                                       21
<PAGE>

                  (d) All fees payable hereunder shall be paid on the dates due,
in immediately available funds, (i) to the Administrative Agent, (ii) to Cisco,
in the case of fees payable to it, or (iii) to the Administrative Agent, in the
case of commitment fees, for distribution to the Lenders entitled thereto. Fees
paid shall not be refundable under any circumstances.

                  SECTION 2.11. INTEREST. (a) The Loans comprising each ABR
Borrowing shall bear interest at the Alternate Base Rate plus the Applicable
Margin.

                  (b) The Loans comprising each LIBOR Borrowing shall bear
interest at the Adjusted LIBO Rate for the Interest Period in effect for such
Borrowing plus the Applicable Margin.

                  (c) Notwithstanding the foregoing, if any Event of Default
occurs (other than an Event of Default described in Section 7.01(f) of the
Common Agreement), then from the date such Event of Default occurs until such
Event of Default is cured or waived, (i) each Loan outstanding shall bear
interest at a rate per annum equal to 2% plus the rate otherwise applicable to
such Loan as provided in the preceding paragraphs of this Section and (ii) all
accrued interest on the Loans, fees and other amounts payable by the Borrower
under the Loan Documents, in each case that is due and payable and has not been
paid, shall bear interest at a rate per annum equal to 2% plus the rate
otherwise applicable to ABR Loans as provided in paragraph (a) of this Section.

                  (d) All accrued interest on each Loan shall be payable in
arrears on each Interest Payment Date for such Loan; PROVIDED that (i) interest
accrued pursuant to paragraph (c) of this Section shall be payable on demand,
(ii) in the event of any repayment or prepayment of any Loan, accrued interest
on the principal amount of such Loan repaid or prepaid shall be payable on the
date of such repayment or prepayment, and (iii) in the event of any conversion
of any Loan prior to the end of the current Interest Period therefor, accrued
interest on such Loan shall be payable on the effective date of such conversion.

                  (e) All interest hereunder shall be computed on the basis of a
year of 360 days, except that interest computed by reference to the Alternate
Base Rate at times when the Alternate Base Rate is based on the Prime Rate shall
be computed on the basis of a year of 365 days (or 366 days in a leap year), and
in each case shall be payable for the actual number of days elapsed (including
the first




                                       22
<PAGE>

day but excluding the last day). The applicable Alternate Base Rate or Adjusted
LIBO Rate shall be determined by the Administrative Agent, and such
determination shall be conclusive absent demonstrable error.

                  SECTION 2.12. ALTERNATE RATE OF INTEREST. If prior to the
commencement of any Interest Period for a LIBOR Borrowing:

                  (a) the Administrative Agent determines (which determination
         shall be conclusive absent demonstrable error) that adequate and
         reasonable means do not exist for ascertaining the Adjusted LIBO Rate
         for such Interest Period; or

                  (b) the Administrative Agent is advised by a majority in
         interest of the Lenders participating in such Borrowing that the
         Adjusted LIBO Rate for such Interest Period will not adequately and
         fairly reflect the cost to such Lenders of making or maintaining their
         Loans included in such Borrowing for such Interest Period;

then the Administrative Agent shall give notice thereof to the Borrower and the
Lenders by telephone (confirmed in writing promptly thereafter) or telecopy as
promptly as practicable thereafter and, until the Administrative Agent notifies
the Borrower and the Lenders that the circumstances giving rise to such notice
no longer exist, (i) any Interest Election Request that requests the conversion
of any Borrowing to, or continuation of any Borrowing as, a LIBOR Borrowing
shall be ineffective and (ii) if any Borrowing Request requests a LIBOR
Borrowing, such Borrowing shall be made as an ABR Borrowing. It is understood
that if Cisco or an Affiliate of Cisco is a Lender participating in a Borrowing,
then such Lender and its Loans included in such Borrowing shall be disregarded
for purposes of clause (b) above except to the extent that participations or
other interests in such Lender's Loans are beneficially owned by other
investors.

                  SECTION 2.13. INCREASED COSTS. (a) If any Change in Law (other
than any Change in Law relating to Taxes, which shall be governed by Section
2.15) shall:

                  (i) impose, modify or deem applicable any reserve, special
         deposit or similar requirement against assets of, deposits with or for
         the account of, or credit extended by, any Lender (except any such
         reserve requirement reflected in the Adjusted LIBO Rate); or



                                       23
<PAGE>

                  (ii) impose on any Lender or the London interbank market any
         other condition affecting this Agreement or LIBOR Loans made by such
         Lender;

and the result of any of the foregoing shall be to increase the cost to such
Lender of making or maintaining any LIBOR Loan (or of maintaining its obligation
to make any such Loan) or to reduce the amount of any sum received or receivable
by such Lender hereunder (whether of principal, interest or otherwise), then the
Borrower will pay to such Lender such additional amount or amounts as will
compensate such Lender for such additional costs incurred or reduction suffered.
It is understood that if Cisco or any Affiliate of Cisco is a Lender, then such
Lender shall not be entitled to the benefits of this Section 2.13 except to the
extent that participations or other interests in such Lender's Loans are
beneficially owned by other investors.

                  (b) If any Lender determines that any Change in Law regarding
capital requirements has or would have the effect of reducing the rate of return
on such Lender's capital or on the capital of such Lender's holding company, if
any, as a consequence of this Agreement or the Loans made by such Lender to a
level below that which such Lender or such Lender's holding company could have
achieved but for such Change in Law (taking into consideration such Lender's
policies and the policies of such Lender's holding company with respect to
capital adequacy), then from time to time the Borrower will pay to such Lender
such additional amount or amounts as will compensate such Lender or such
Lender's holding company for any such reduction suffered.

                  (c) A certificate of a Lender setting forth the amount or
amounts necessary to compensate such Lender or its holding company, as the case
may be, as specified in paragraph (a) or (b) of this Section and an explanation
of the basis therefor shall be delivered to the Borrower and shall be conclusive
absent demonstrable error. The Borrower shall pay such Lender the amount shown
as due on any such certificate within 30 days after receipt thereof.

                  (d) Failure or delay on the part of any Lender to demand
compensation pursuant to this Section shall not constitute a waiver of such
Lender's right to demand such compensation; PROVIDED that the Borrower shall not
be required to compensate a Lender pursuant to this Section for any increased
costs or reductions incurred more than 270 days prior to the date that such
Lender notifies Holdings or the Borrower of the Change in Law giving rise to
such increased costs or reductions and of such Lender's intention to claim
compensation therefor; PROVIDED FURTHER that, if



                                       24
<PAGE>

the Change in Law giving rise to such increased costs or reductions is
retroactive, then the 270-day period referred to above shall be extended to
include the period of retroactive effect thereof.

                  SECTION 2.14. BREAK FUNDING PAYMENTS. In the event of (a) the
payment of any principal of any LIBOR Loan other than on the last day of an
Interest Period applicable thereto (including as a result of an Event of
Default), (b) the conversion of any LIBOR Loan other than on the last day of the
Interest Period applicable thereto, (c) the failure to borrow, convert, continue
or prepay any Loan on the date specified in any notice delivered pursuant
hereto, or (d) the assignment of any LIBOR Loan other than on the last day of
the Interest Period applicable thereto as a result of a request by the Borrower
pursuant to Section 2.17, then, in any such event, the Borrower shall compensate
each Lender for the loss, cost and expense attributable to such event. In the
case of a LIBOR Loan, such loss, cost or expense to any Lender shall be deemed
to include an amount determined by such Lender to be the excess, if any, of (i)
the amount of interest which would have accrued on the principal amount of such
Loan had such event not occurred, at the Adjusted LIBO Rate that would have been
applicable to such Loan, for the period from the date of such event to the last
day of the then current Interest Period therefor (or, in the case of a failure
to borrow, convert or continue, for the period that would have been the Interest
Period for such Loan), over (ii) the amount of interest which would accrue on
such principal amount for such period at the interest rate which such Lender
would bid were it to bid, at the commencement of such period, for Dollar
deposits of a comparable amount and period from other banks in the eurodollar
market. If a Lender is not a commercial bank, such Lender may determine amounts
due to it pursuant to the preceding sentence by any other reasonable method
designed to calculate funding losses for the relevant Interest Period. A
certificate of any Lender setting forth in reasonable detail the basis for any
amount or amounts that such Lender is entitled to receive pursuant to this
Section shall be delivered to the Borrower and shall be conclusive absent
demonstrable error. The Borrower shall pay such Lender the amount shown as due
on any such certificate within 30 days after receipt thereof.

                  SECTION 2.15. TAXES. (a) Any and all payments by or on account
of any obligation of the Borrower hereunder or under any other Loan Document
shall be made free and clear of and without deduction for any Indemnified Taxes
or Other Taxes; PROVIDED that if the Borrower shall be required to deduct any
Indemnified Taxes or Other Taxes from such




                                       25
<PAGE>

payments, then (i) the sum payable shall be increased as necessary so that after
making all required deductions (including deductions applicable to additional
sums payable under this Section) the Administrative Agent or Lender receives an
amount equal to the sum it would have received had no such deductions been made,
(ii) the Borrower shall make such deductions and (iii) the Borrower shall pay
the full amount deducted to the relevant Governmental Authority in accordance
with applicable law.

                  (b) In addition, the Borrower shall pay any Other Taxes to the
relevant Governmental Authority in accordance with applicable law.

                  (c) The Borrower shall indemnify the Administrative Agent and
each Lender, within 10 days after written demand therefor, for the full amount
of any Indemnified Taxes or Other Taxes paid by the Administrative Agent or such
Lender on or with respect to any payment by or on account of any obligation of
the Borrower hereunder or under any other Loan Document (including Indemnified
Taxes or Other Taxes imposed or asserted on or attributable to amounts payable
under this Section) and any penalties, interest and reasonable expenses arising
therefrom or with respect thereto, whether or not such Indemnified Taxes or
Other Taxes were correctly or legally imposed or asserted by the relevant
Governmental Authority. A certificate including a reasonably detailed
calculation as to the amount of such payment or liability delivered to the
Borrower by a Lender, or by the Administrative Agent on its own behalf or on
behalf of a Lender, shall be conclusive absent demonstrable error.

                  (d) As soon as practicable after any payment of Indemnified
Taxes or Other Taxes by the Borrower to a Governmental Authority, the Borrower
shall deliver to the Administrative Agent the original or a certified copy of a
receipt issued by such Governmental Authority evidencing such payment, a copy of
the return reporting such payment or other evidence of such payment reasonably
satisfactory to the Administrative Agent.

                  (e) Any Foreign Lender that is entitled to an exemption from
or reduction of withholding tax under the law of the jurisdiction in which the
Borrower is located, or any treaty to which such jurisdiction is a party, with
respect to payments under this Agreement shall deliver to the Borrower (with a
copy to the Administrative Agent), at the time or times prescribed by applicable
law, such properly completed and executed documentation prescribed by applicable
law or reasonably requested by the Borrower as




                                       26
<PAGE>

will permit such payments to be made without withholding or at a reduced rate;
PROVIDED that such Foreign Lender has received written notice from the Borrower
advising it of the availability of such exemption or reduction and supplying all
applicable documentation.

                  (f) If a Lender changes its applicable lending office (other
than pursuant to Section 2.17) and the effect of the change, as of the date of
the change, would be to cause the Borrower to become obligated to pay any
greater amount under Section 2.13 or 2.15 than it would otherwise have been
obligated to pay the Lender as of such date, then the Borrower shall not be
obligated to pay such greater amount.

                  (g) If any Agent or Lender determines in good faith that it
has received a refund of Indemnified Taxes or Other Taxes for which the Borrower
has made payments pursuant to this Section 2.15 which such Agent or Lender is
able to identify as such, then such Agent or Lender, as the case may be, shall
promptly pay such refund (but only to the extent of any indemnity payments made
by the Borrower pursuant to this Section 2.15 with respect to the Indemnified
Taxes or Other Taxes giving rise to such refund) net of all out-of-pocket
expenses of such Agent or Lender and without interest (other than any interest
with respect to such refund received from the relevant Governmental Authority)
to the Borrower; PROVIDED, HOWEVER, that the Borrower agrees promptly to return
such refund (together with any interest, penalties or other charges with respect
thereto due to the relevant Governmental Authority) to such Agent or the
applicable Lender, as the case may be, upon receipt of a notice that such refund
is required to be repaid to the relevant Governmental Authority. Notwithstanding
anything to the contrary contained in this clause (g), no Lender or Agent shall
have any obligation to disclose any of such Person's books, records or tax
filings (or any other information relating to Taxes which it deems confidential)
to the Borrower or any other Person.

                  SECTION 2.16. PAYMENTS GENERALLY; PRO RATA TREATMENT. (a) The
Borrower shall make each payment required to be made by it hereunder (whether of
principal, interest or fees, or of amounts payable under Section 2.13, 2.14 or
2.15, or otherwise) prior to 12:00 (noon), New York City time, on the date when
due, in immediately available funds, without set-off or counterclaim. Any
amounts received after such time on any date may, in the discretion of the
Administrative Agent, be deemed to have been received on the next succeeding
Business Day for purposes of calculating interest thereon. All such payments
shall be made to




                                       27
<PAGE>

the Administrative Agent at such account in New York, New York as the
Administrative Agent shall from time to time specify by notice, except that
payments pursuant to Sections 2.10(b), 2.10(c), 2.13, 2.14, 2.15 and 9.03 shall
be made directly to the Persons entitled thereto. The Administrative Agent shall
distribute any such payments received by it for the account of any other Person
to the appropriate recipient promptly following receipt thereof. If any payment
under this Agreement shall be due on a day that is not a Business Day, the date
for payment shall be extended to the next succeeding Business Day, and, in the
case of any payment accruing interest, interest thereon shall be payable for the
period of such extension. All payments under this Agreement shall be made in
Dollars.

                  (b) Each repayment or prepayment of principal of the Loans
hereunder, or selection of Borrowings for repayment or prepayment, shall be made
such that the benefit of such repayment or prepayment is shared by the Lenders
ratably in accordance with the aggregate principal amount of their respective
Loans then outstanding. Each reduction of the Commitments hereunder shall be
made such that the benefit of such reduction is shared by the Lenders ratably in
accordance with the aggregate principal amount of their respective Commitments
then outstanding, except as otherwise required by Article II of the Common
Agreement.

                  (c) If at any time insufficient funds are received by and
available to the Administrative Agent to pay fully all amounts of principal,
interest and fees then due hereunder, such funds shall be applied (i) first,
towards payment of interest and fees then due hereunder, ratably among the
parties entitled thereto in accordance with the amounts of interest and fees
then due to such parties, and (ii) second, towards payment of principal then due
hereunder, ratably among the parties entitled thereto in accordance with the
amounts of principal then due to such parties.

                  (d) Unless the Administrative Agent shall have received notice
from the Borrower prior to the date on which any payment is due to the
Administrative Agent for the account of the Lenders hereunder that the Borrower
will not make such payment, the Administrative Agent may assume that the
Borrower has made such payment on such date in accordance herewith and may, in
reliance upon such assumption, distribute to the Lenders the amount due. In such
event, if the Borrower has not in fact made such payment, then each of the
Lenders severally agrees to repay to the Administrative Agent forthwith on
demand the amount so distributed to such Lender with interest thereon, for each
day from and including the date such amount is distributed to it to but



                                       28
<PAGE>

excluding the date of payment to the Administrative Agent, at the greater of the
Federal Funds Effective Rate and a rate determined by the Administrative Agent
in accordance with banking industry rules on interbank compensation.

                  (e) Without limiting the generality of paragraph (a) above,
the Borrower's obligations to make each payment required to be made by it
hereunder or under any other Loan Document (whether of principal, interest, fees
or otherwise) shall be absolute and unconditional and shall not be subject to
any delay, reduction, set-off, counterclaim, defense or recoupment for any
reason, including any dispute with, breach of representation or warranty by or
claim against any supplier, manufacturer, installer, vendor or distributor,
including Cisco.

                  (f) Notwithstanding the foregoing, the Lenders acknowledge and
agree that they shall have no recourse against the Borrower's statutory capital,
in a maximum aggregate amount of EURO 18,000, in respect of the Loans; PROVIDED
that, for purposes hereof (i) such statutory capital shall be deemed to be
represented by the last remaining assets of the Borrower, and recourse to the
Borrower's assets shall not be limited or otherwise impaired or restricted until
all other assets of the Borrower have been exhausted and (ii) the Collateral
shall not be deemed to include such statutory capital.

                  SECTION 2.17. MITIGATION OBLIGATIONS; REPLACEMENT OF LENDERS.
(a) If any Lender requests compensation under Section 2.13, or if the Borrower
is required to pay any additional amount to any Lender, any Agent or any
Governmental Authority for the account of any Lender or any Agent pursuant to
Section 2.15, then such Lender or Agent shall use all commercially reasonable
efforts to designate a different lending office for funding or booking its Loans
hereunder or to assign its rights and obligations hereunder to another of its
offices, branches or affiliates, if, in the reasonable judgment of such Lender
or Agent, such designation or assignment (i) would eliminate or reduce amounts
payable pursuant to Section 2.13 or 2.15, as the case may be, in the future and
(ii) would not subject such Lender or Agent to any unreimbursed cost or expense
and would not otherwise be disadvantageous to such Lender or Agent. The Borrower
hereby agrees to pay all reasonable costs and expenses incurred by any Lender or
any Agent in connection with any such designation or assignment.

                  (b)  If any Lender requests compensation under Section 2.13,
or if the Borrower is required to pay any



                                       29
<PAGE>



additional amount to any Lender or any Governmental Authority for the account of
any Lender pursuant to Section 2.15, then the Borrower may, at its sole expense
and effort, upon notice to such Lender and the Administrative Agent, require
such Lender to assign and delegate, without recourse (in accordance with and
subject to the restrictions contained in Section 9.04), all its interests,
rights and obligations under this Agreement to an assignee that shall assume
such obligations (which assignee may be another Lender, if a Lender accepts such
assignment); PROVIDED that (i) unless the requesting Lender is an Affiliate of
the Administrative Agent, the Borrower shall have received the prior written
consent of the Administrative Agent, which consent shall not unreasonably be
withheld, (ii) such Lender shall have received payment of an amount equal to the
outstanding principal of its Loans, accrued interest thereon, accrued fees and
all other amounts payable to it hereunder, from the assignee (to the extent of
such outstanding principal and accrued interest and fees) or the Borrower (in
the case of all other amounts), or such lesser or greater amounts as may be
agreed by such Lender in its sole and absolute discretion, and (iii) such
assignment will result in a material reduction in such compensation or payments.
A Lender shall not be required to make any such assignment and delegation if,
prior thereto, as a result of a waiver by such Lender or otherwise, the
circumstances entitling the Borrower to require such assignment and delegation
cease to apply.

Lender to make a Loan on the occasion of



                                       30
<PAGE>

any Borrowing is subject to the satisfaction of the conditions set forth in
Section 4.02 of the Common Agreement.

                  (b) In addition, no Lender shall be required to make a Tranche
B Loan on the occasion of any Tranche B Borrowing if, after giving effect to all
Loans requested to be made hereunder on the date of such Borrowing, the
aggregate principal amount of Tranche B Loans outstanding hereunder would exceed
50% of the aggregate principal amount of Tranche A Loans outstanding hereunder
on such date.

                  (c) Each Borrowing shall be deemed to constitute a
representation and warranty by each of Holdings and the Borrower on the date
thereof as to the matters set forth in Section 4.02 of the Common Agreement and
in paragraph (b) of this Section 4.02.

                                    ARTICLE V
                              AFFIRMATIVE COVENANTS

                  SECTION 5.01. COVENANTS CONTAINED IN THE COMMON AGREEMENT.

Loans will be applied solely (i) to make the payments due to Cisco for the
Purchase Price of Qualifying Purchases pursuant to the Cisco Supply Contract,
(ii) in the case of Tranche A Loans made on the Effective Date, to pay amounts
set forth on Schedule 5.02(a) owing by the Loan Parties to Cisco and its

forth on Schedule 5.02(b) representing amounts paid to Cisco prior to the date

under this Agreement may be used, directly or indirectly, to finance the
purchase of equipment or services provided by a Competitor of Cisco (including

                                   ARTICLE VI

                  The Events of Default hereunder shall be as provided in
Article VII of the Common Agreement. Upon the occurrence of any such Event of
Default (other than an event with respect to the Borrower or Holdings described
in clause (i), (j) or (k) of Section 7.01 of the Common Agreement), and at any
time thereafter during the continuance of such event, the Administrative Agent
may, and at the request of the Required Enforcement Lenders shall, by notice to
the Borrower, take either or both of the following actions, at the same or
different times: (i) terminate the Commitments, and thereupon the Commitments
shall terminate immediately, and (ii) declare the Loans then outstanding to be
due and payable in whole (or in part, in which case any principal not so
declared to be due and payable may thereafter be declared to be due and
payable), and thereupon the principal of the Loans so declared to be due and
payable, together with accrued interest thereon and all fees and other
obligations of the Borrower owing to any of the Agents and the Lenders accrued
under the Loan Documents, shall become due and payable immediately, without
presentment, demand, protest or other notice of any kind,




                                       33
<PAGE>

all of which are hereby waived by the Borrower; and in case of any event with
respect to the Borrower or Holdings described in clause (i), (j) or (k) of
Section 7.01 of the Common Agreement, the Commitments shall automatically
terminate and the principal of the Loans then outstanding, together with accrued
interest thereon and all fees and other obligations of the Borrower owing to any
of the Agents and the Lenders accrued under the Loan Documents, shall
automatically become due and payable, without presentment, demand, protest or
other notice of any kind, all of which are hereby waived by the Borrower. If any
Loans are declared due and payable pursuant to clause (ii) above or if the
Collateral Agent commences the exercise of remedies under any of the Security
Documents to foreclose upon or sell any Collateral while an Event of Default has
occurred and is continuing, then the Commitments shall automatically terminate.

                                  ARTICLE VIII
                                   THE AGENTS

                  Each of the Lenders hereby irrevocably appoints the
Administrative Agent as its agent and authorizes the Administrative Agent to
take such actions on its behalf and to exercise such powers as are delegated to
the Administrative Agent by the terms of the Loan Documents, together with such
actions and powers as are reasonably incidental thereto.

                  Any Person serving as Administrative Agent hereunder shall
have the same rights and powers in its capacity as a Lender as any other Lender
and may exercise the same as though it were not the Administrative Agent, and
such Person and its Affiliates may accept deposits from, lend money to and
generally engage in any kind of business with Holdings, the Borrower, any
Subsidiary or any other Affiliate of Holdings as if it were not the
Administrative Agent hereunder.

                  The Administrative Agent shall not have any duties or
obligations except those expressly set forth in the Loan Documents. Without
limiting the generality of the foregoing, (a) the Administrative Agent shall not
be subject to any fiduciary or other implied duties, regardless of whether a
Default has occurred and is continuing, (b) the Administrative Agent shall not
have any duty to take any discretionary action or exercise any discretionary
powers, except discretionary rights and powers expressly contemplated by the
Loan Documents that the Administrative



                                       34
<PAGE>

Agent is required to exercise in writing by the Required Lenders (or such other
number or percentage of the Lenders as shall be necessary under the
circumstances as provided in Section 9.02 or Article VII), and (c) except as
expressly set forth in the Loan Documents, the Administrative Agent shall not
have any duty to disclose, and shall not be liable for the failure to disclose,
any information relating to any of the Loan Parties that is communicated to or
obtained by the Person serving as Administrative Agent or any of its Affiliates
in any capacity. The Administrative Agent shall not be liable for any action
taken or not taken by it with the consent or at the request of the Required
Lenders (or such other number or percentage of the Lenders as shall be necessary
under the circumstances as provided in Section 9.02 or Article VII) or in the
absence of its own gross negligence or wilful misconduct. The Administrative
Agent shall be deemed not to have knowledge of any Default unless and until
written notice thereof is given to it by Holdings, the Borrower or a Lender, and
the Administrative Agent shall not be responsible for or have any duty to
ascertain or inquire into (i) any statement, warranty or representation made in
or in connection with any Loan Document, (ii) the contents of any certificate,
report or other document delivered thereunder or in connection therewith, (iii)
the performance or observance of any of the covenants, agreements or other terms
or conditions set forth in any Loan Document, (iv) the validity, enforceability,
effectiveness or genuineness of any Loan Document or any other agreement,
instrument or document, or (v) the satisfaction of any condition set forth or
referred to in Article IV hereof or elsewhere in any Loan Document, other than
to confirm receipt of items expressly required to be delivered to the
Administrative Agent.

                  The Administrative Agent shall be entitled to rely upon, and
shall not incur any liability for relying upon, any notice, request,
certificate, consent, statement, instrument, document or other writing believed
by it to be genuine and to have been signed or sent by the proper Person. Except
to the extent that the provisions hereof require writings, the Administrative
Agent also may rely upon any statement made to it orally or by telephone and
believed by it to be made by the proper Person, and shall not incur any
liability for relying thereon. The Administrative Agent may consult with legal
counsel (who may be counsel for Holdings or the Borrower), independent
accountants and other experts selected by it, and shall not be liable for any
action taken or not taken by it in accordance with the advice of any such
counsel, accountants or experts.


                                       35
<PAGE>

                  The Administrative Agent may perform any and all its duties
and exercise its rights and powers by or through any one or more sub-agents
appointed by the Administrative Agent; PROVIDED that neither Holdings nor the
Borrower shall, without its consent, be liable for any fees payable to any such
sub-agent, except for any fees payable in connection with the exercise of rights
or remedies when an Event of Default has occurred and is continuing. The
Administrative Agent and any such sub-agent may perform any and all its duties
and exercise its rights and powers through their respective Related Parties. The
exculpatory provisions of the preceding paragraphs shall apply to any such
sub-agent and to the Related Parties of the Administrative Agent and any such
sub-agent, and shall apply to their respective activities in connection with the
syndication of the credit facilities provided for herein as well as activities
as Administrative Agent.

                  Subject to the appointment and acceptance of a successor
Administrative Agent as provided in this paragraph, the Administrative Agent may
resign at any time by notifying the Lenders and the Borrower. Upon any such
resignation, the Required Lenders shall have the right to appoint a successor.
If no successor shall have been so appointed by the Required Lenders and shall
have accepted such appointment within 30 days after the retiring Administrative
Agent gives notice of its resignation, then the retiring Administrative Agent
may, on behalf of the Lenders, appoint a successor Administrative Agent which
shall be a commercial bank with an office in New York, New York, or an Affiliate
of any such bank. Upon the acceptance of its appointment as Administrative Agent
hereunder by a successor, such successor shall succeed to and become vested with
all the rights, powers, privileges and duties of the retiring Administrative
Agent, and the retiring Administrative Agent shall be discharged from its duties
and obligations hereunder. The retiring or removed Administrative Agent shall
provide to its successor the original or true and accurate copies of all of its
books and records relating to this Agreement and the transactions contemplated
hereby. The fees payable by the Borrower to a successor Administrative Agent
shall be the same as those payable to its predecessor unless otherwise agreed
between the Borrower and such successor. After the Administrative Agent's
resignation hereunder, the provisions of this Article and Section 9.03 shall
continue in effect for the benefit of such retiring Administrative Agent, its
sub-agents and their respective Related Parties in respect of any actions taken
or omitted to be taken by any of them while it was acting as Administrative
Agent.

                  Each Lender acknowledges that it has, independently and
without reliance upon the Administrative Agent or any other Lender and based on
such documents and information as it has deemed appropriate, made its own credit
analysis and decision to enter into this Agreement. Each Lender also
acknowledges that it will, independently and without reliance upon the
Administrative Agent or any other Lender and based on such documents and
information as it shall from time to time deem appropriate, continue to make its
own decisions in taking or not taking action under or based upon this Agreement,
any other Loan Document or related agreement or any document furnished hereunder
or thereunder.

                  Each Lender acknowledges and agrees to the terms of the
Collateral Agency Agreement and to the appointment of the Collateral Agent to
act as collateral agent under the Collateral Agency Agreement and the other Loan
Documents, and each Lender hereby acknowledges and assumes all of the duties of
a Secured Party as set forth in the Collateral Agency Agreement. Each Lender
further agrees that, should Holdings or the Borrower fail to pay any costs or
expenses of the Collateral Agent under Section 7.02(a) of the Collateral Agency
Agreement, such Lender shall, promptly upon the demand in writing of the
Collateral Agent, pay to the Collateral Agent such Lender's pro rata share of
such costs.

         (Telecopy No. (212) 797-0407);

                  (d) if to Cisco, to it at 8200 NW 41st Street,
         Suite 400, Miami, FL 33166, Attention of Oscar Bode
         (Telecopy No. (305) 718-2699); and

                  (e) if to any other Lender, to it at its address
         (or telecopy number) set forth in its Administrative
         Questionnaire.

Any party hereto may change its address or telecopy number for notices and other
communications hereunder by notice to the other parties hereto. All notices and
other communications given to any party hereto in accordance with the
provisions of this Agreement shall be deemed to have been given on the date of
receipt.

                  SECTION 9.02. WAIVERS; AMENDMENTS. (a) No failure or delay by
either Agent or any Lender in exercising any right or power hereunder or under
any other Loan Document shall operate as a waiver thereof, nor shall any single
or partial exercise of any such right or power, or any abandonment or
discontinuance of steps to enforce such a right or power, preclude any other or
further exercise thereof or the exercise of any other right or power. The rights
and remedies of the Agents and the Lenders hereunder and under the other Loan
Documents are cumulative and are not exclusive of any rights or remedies that
they would otherwise have. No waiver of any provision of this Agreement or
consent to any departure by any Loan Party therefrom shall in any event be
effective unless the same shall be permitted by paragraph (b) of this Section,
and then such waiver or consent shall be effective only in the specific instance
and for the purpose for which given. Without limiting the generality of the
foregoing, the making of a Loan shall not be construed as a waiver of any
Default, regardless of whether an Agent or any Lender may have had notice or
knowledge of such Default at the time.

                  (b) Neither this Agreement nor any provision hereof may be
waived, amended or modified except pursuant to an agreement or agreements in
writing entered into by Holdings, the Borrower and the Required Lenders;
PROVIDED that no such agreement shall (i) increase the Commitment of any Lender
without the written consent of such Lender, (ii) reduce the principal amount of
any Loan or reduce the rate of interest on such Loan, or reduce any fees payable
hereunder, without the written consent of each Lender



                                       38
<PAGE>

affected thereby, (iii) postpone the scheduled date of payment of the principal
amount of any Loan or any interest thereon, or any fees payable hereunder, or
reduce the amount of, waive or excuse any such payment, or postpone the
scheduled date of expiration of any Commitment, without the written consent of
each Lender affected thereby, (iv) change Section 2.16(b) or (c) in a manner
that would alter the pro rata sharing of payments required thereby, without the
written consent of each Lender, (v) change any of the provisions of this Section
9.02(b) or the definition of "Required Lenders" or "Required Enforcement
Lenders" or any other provision hereof specifying the number or percentage of
Lenders required to waive, amend or modify any rights thereunder or make any
determination or grant any consent thereunder, without the written consent of
each Lender or (vi) so long as any Cisco Lender has any Commitment, change
Section 5.02 without the written consent of Cisco (in addition to the consent of
the Required Lenders); PROVIDED FURTHER that no such agreement shall amend,
modify or otherwise affect the rights or duties of either Agent without the
prior written consent of such Agent. In addition, any waiver, amendment or
modification to this Agreement shall be subject to compliance with Section 8.02
of the Collateral Agency Agreement.

                  SECTION 9.03. EXPENSES; INDEMNITY; DAMAGE WAIVER. (a) The
Borrower shall pay costs and expenses and shall indemnify the Administrative
Agent and each Lender and each Related Party of any of the foregoing Persons as
provided in Section 8.03(a) and Section 8.03(b) of the Common Agreement. Neither
the Borrower nor Holdings shall assert and each of them agrees to waive claims
and damages as provided in Section 8.03(c) of the Common Agreement. All amounts
due under this Section shall be payable as provided in Section 8.03(d) of the
Common Agreement.

                  (b) To the extent that the Borrower fails to pay any amount
required to be paid by it to the Administrative Agent as provided in Section
8.03(a) and Section 8.03(b) of the Common Agreement, each Lender severally
agrees to pay to the Administrative Agent such Lender's pro rata share
(determined as of the time that the applicable unreimbursed expense or indemnity
payment is sought) of such unpaid amount; PROVIDED that the unreimbursed expense
or indemnified loss, claim, damage, liability or related expense, as the case
may be, was incurred by or asserted against the Administrative Agent in its
capacity as such. For purposes hereof, a Lender's "pro rata share" shall be
determined based upon its share of the sum of the total outstanding Loans and
unused Commitments at the time.

                  SECTION 9.04. SUCCESSORS AND ASSIGNS. (a) The provisions of
this Agreement shall be binding upon and inure to the benefit of the parties
hereto and their respective successors and assigns permitted hereby, except that
the Borrower may not assign or otherwise transfer any of its rights or
obligations hereunder without the prior written consent of each Lender (and any
attempted assignment or transfer by the Borrower without such consent shall be
null and void). Nothing in this Agreement, expressed or implied, shall be
construed to confer upon any Person (other than the parties hereto, their
respective successors and assigns permitted hereby and, to the extent expressly
contemplated hereby, the Related Parties of each of the Agents and the Lenders)
any legal or equitable right, remedy or claim under or by reason of this
Agreement.

                  (b) Any Lender may assign to one or more assignees all or a
portion of its rights and obligations under this Agreement (including all or a
portion of its Commitment and the Loans at the time owing to it); PROVIDED that
(i) except in the case of an assignment to Cisco, a Lender or an Affiliate of
Cisco or of a Lender, the Administrative Agent must give its prior written
consent to such assignment (which consent shall not be unreasonably withheld or
delayed), (ii) in the case of an assignment to any Person other than an Eligible
Assignee, the Borrower must give its prior written consent to such assignment
(which consent shall not be unreasonably withheld or delayed), (iii) except in
the case of an assignment to Cisco, a Lender or an Affiliate of Cisco or a
Lender or an assignment of the entire remaining amount of the assigning Lender's
Commitment and Loans, the amount of the Commitment and Loans of the assigning
Lender subject to each such assignment (determined as of the date the Assignment
and Acceptance with respect to such assignment is delivered to the
Administrative Agent) shall not be less than $1,000,000 unless the Borrower
otherwise consents, (iv) each partial assignment shall be made as an assignment
of a proportionate part of all the assigning Lender's rights and obligations
under this Agreement (except that this clause shall not prohibit the assignment
of a Fronting Commitment as contemplated by Section 2.02), except that this
clause shall not be construed to prohibit the assignment of a proportionate part
of all of the assigning Lender's rights and obligations in respect of (A) Loans
separately from (or without assigning) Commitments, (B) Commitments separately
from (or without assigning) Loans or (C) Loans or Commitments of any Class
separately from (or without assigning) Loans or Commitments of any other Class,
(v) the parties to each assignment shall execute and deliver to the
Administrative Agent with a copy to the Borrower an Assignment and Acceptance,
together with


                                       40
<PAGE>

a processing and recordation fee of $3,500, (vi) the assignee, if it shall not
be a Lender, shall deliver to the Administrative Agent an Administrative
Questionnaire and (vii) the assignee shall make the representations and
warranties (which shall be included in the Assignment and Acceptance required by
clause (v) above) set forth on Schedule 9.04(b), except that the representation
and warranty contained in clause (a) of the last paragraph thereof shall only be
required until an ICA Exemption Order is obtained; PROVIDED FURTHER that any
consent of the Borrower otherwise required under this paragraph shall not be
required if an Event of Default has occurred and is continuing. Subject to
acceptance and recording thereof pursuant to paragraph (d) of this Section, from
and after the effective date specified in each Assignment and Acceptance the
assignee thereunder shall be a party hereto and, to the extent of the interest
assigned by such Assignment and Acceptance, have the rights and obligations of a
Lender under this Agreement, and the assigning Lender thereunder shall, to the
extent of the interest assigned by such Assignment and Acceptance, be released
from its obligations under this Agreement (and, in the case of an Assignment
and Acceptance covering all of the assigning Lender's rights and obligations
under this Agreement, such Lender shall cease to be a party hereto but shall
continue to be entitled to the benefits of Sections 2.13, 2.14, 2.15 and 9.03).
Notwithstanding the foregoing, no assignee shall be entitled to receive any
greater payment under Section 2.13 or 2.15 than the assigning Lender would have
been entitled to receive as of the date of assignment with respect to the rights
assigned, unless the Borrower has consented in writing to the assignment. Any
assignment or transfer by a Lender of rights or obligations under this Agreement
that does not comply with this paragraph shall be treated for purposes of this
Agreement as a sale by such Lender of a participation in such rights and
obligations in accordance with paragraph (e) of this Section.

                  (c) The Administrative Agent, acting for this purpose as an
agent of the Borrower, shall maintain at one of its offices a copy of each
Assignment and Acceptance delivered to it and a register for the recordation of
the names and addresses of the Lenders, and the Commitments of, and principal
amount of the Loans owing to, each Lender pursuant to the terms hereof from time
to time (the "REGISTER"). The entries in the Register shall be conclusive, and
Holdings, the Borrower, the Agents and the Lenders may treat each Person whose
name is recorded in the Register pursuant to the terms hereof as a Lender
hereunder for all purposes of this Agreement, notwithstanding notice to the
contrary. The Register shall be available for inspection by



                                       41
<PAGE>

Holdings, the Borrower and any Lender, at any reasonable time and from time to
time upon reasonable prior notice.

                  (d) Upon its receipt of a duly completed Assignment and
Acceptance executed by an assigning Lender and an assignee, the assignee's
completed Administrative Questionnaire (unless the assignee shall already be a
Lender hereunder), the processing and recordation fee referred to in paragraph
(b) of this Section and any written consent to such assignment required by
paragraph (b) of this Section, the Administrative Agent shall accept such
Assignment and Acceptance and record the information contained therein in the
Register. No assignment shall be effective for purposes of this Agreement unless
it has been recorded in the Register as provided in this paragraph.

                  (e) Any Lender may, without the consent of the Borrower or the
Administrative Agent, sell participations to one or more banks or other entities
(a "PARTICIPANT") in all or a portion of such Lender's rights and obligations
under this Agreement (including all or a portion of its Commitments and the
Loans owing to it); PROVIDED that (i) such Lender's obligations under this
Agreement shall remain unchanged, (ii) such Lender shall remain solely
responsible to the other parties hereto for the performance of such obligations,
(iii) Holdings, the Borrower, the Agents and the other Lenders shall continue to
deal solely and directly with such Lender in connection with such Lender's
rights and obligations under this Agreement and (iv) no Lender may sell any such
participation to a Competitor of Holdings and its Subsidiaries without the prior
written consent of the Borrower unless the Loans have become or been declared
immediately due and payable pursuant to Article VII. Any agreement or instrument
pursuant to which a Lender sells such a participation shall provide that such
Lender shall retain the sole right to enforce the Loan Documents and to approve
any amendment, modification or waiver of any provision of the Loan Documents;
PROVIDED that such agreement or instrument may provide that such Lender will
not, without the consent of the Participant, agree to any amendment,
modification or waiver described in the first proviso to Section 9.02(b) that
affects such Participant. Subject to paragraph (f) of this Section, the Borrower
agrees that each Participant shall be entitled to the benefits of Sections 2.13,
2.14 and 2.15 to the same extent as if it were a Lender and had acquired its
interest by assignment pursuant to paragraph (b) of this Section. To the extent
permitted by law, each Participant also shall be entitled to the benefits of
Section 9.08 as though it were a Lender, provided such Participant agrees to be
subject to


                                       42
<PAGE>

Section 9.10 of the Collateral Agency Agreement as though it were a Lender.

                  (f) A Participant that would be a Foreign Lender if it were a
Lender shall not be entitled to the benefits of Section 2.15 unless the Borrower
is notified of the participation sold to such Participant and such Participant
agrees, for the benefit of the Borrower, to comply with Section 2.15(e) and (g)
as though it were a Lender. In addition, a Participant shall be entitled to
receive amounts under Sections 2.13 and 2.15 only to the extent that, and in no
greater amount than, the Lender selling the participation would be entitled to
receive if the participation had not been entered into or sold unless the sale
of the participation to such Participant is made with the Borrower's prior
written consent (and in any event without duplication of amounts payable to such
Lender pursuant to Section 2.13 or 2.15 after the sale of such participation
with respect to the participation sold).

                  (g) Any Lender may at any time pledge or assign a security
interest in all or any portion of its rights under this Agreement to secure
obligations of such Lender, including any pledge or assignment to secure
obligations to a Federal Reserve Bank, and this Section shall not apply to any
such pledge or assignment of a security interest; PROVIDED that (i) no such
pledge or assignment of a security interest shall release a Lender from any of
its obligations hereunder or (whether or not a foreclosure on such rights has
been made) substitute any such pledgee or assignee for such Lender as a party
hereto and (ii) no such pledgee or assignee shall be a Competitor of Holdings
unless an Event of Default has occurred and is continuing at the time of such
pledge or assignment.

                  (h) The Borrower agrees to use its commercially reasonable
efforts to obtain an ICA Exemption Order as promptly as practicable following
the Effective Date.

                  SECTION 9.05. SURVIVAL. All covenants, agreements,
representations and warranties made by the Loan Parties in the Loan Documents
and in the certificates or other instruments delivered in connection with or
pursuant to this Agreement or any other Loan Document shall be considered to
have been relied upon by the other parties hereto and shall survive the
execution and delivery of the Loan Documents and the making of any Loans,
regardless of any investigation made by any such other party or on its behalf
and notwithstanding that either Agent or any Lender may have had notice or
knowledge of any Default or incorrect representation or warranty at the time any
credit is



                                       43
<PAGE>

extended hereunder, and shall continue in full force and effect as long as the
principal of or any accrued interest on any Loan or any fee or any other amount
payable under this Agreement is outstanding and unpaid and so long as the
Commitments have not expired or terminated. The provisions of Sections 2.13,
2.14, 2.15 and 9.03 and Article VIII shall survive and remain in full force and
effect regardless of the consummation of the transactions contemplated hereby,
the repayment of the Loans, the expiration or termination of the Commitments or
the termination of this Agreement or any provision hereof.

                  SECTION 9.06. COUNTERPARTS; INTEGRATION; EFFECTIVENESS. This
Agreement may be executed in counterparts (and by different parties hereto on
different counterparts), each of which shall constitute an original, but all of
which when taken together shall constitute a single contract. This Agreement,
the other Loan Documents and any separate letter agreements with respect to the
agreement of Holdings and the Borrower to cooperate with Cisco with respect to
marketing, selling or syndicating Loans and Commitments or with respect to fees
payable to Cisco or either Agent constitute the entire contract among the
parties relating to the subject matter hereof and supersede any and all previous
agreements and understandings, oral or written, relating to the subject matter
hereof. Except as provided in Section 4.01, this Agreement shall become
effective when it shall have been executed by the Administrative Agent and when
the Administrative Agent shall have received counterparts hereof which, when
taken together, bear the signatures of each of the other parties hereto, and
thereafter shall be binding upon and inure to the benefit of the parties hereto
and their respective successors and assigns. Delivery of an executed counterpart
of a signature page of this Agreement by telecopy shall be effective as delivery
of a manually executed counterpart of this Agreement.

                  SECTION 9.07. SEVERABILITY. Any provision of this Agreement
held to be invalid, illegal or unenforceable in any jurisdiction shall, as to
such jurisdiction, be ineffective to the extent of such invalidity, illegality
or unenforceability without affecting the validity, legality and enforceability
of the remaining provisions hereof; and the invalidity of a particular provision
in a particular jurisdiction shall not invalidate such provision in any other
jurisdiction.

                  SECTION 9.08. RIGHT OF SETOFF. If an Event of Default shall
have occurred and be continuing, each Lender and each of its Affiliates is
hereby authorized at any time


                                       44
<PAGE>

and from time to time, to the fullest extent permitted by law, to set off and
apply any and all deposits (general or special, time or demand, provisional or
final) at any time held and other obligations at any time owing by such Lender
or Affiliate to or for the credit or the account of Holdings or the Borrower
against any of and all the obligations of Holdings or the Borrower now or
hereafter existing under this Agreement held by such Lender, irrespective of
whether or not such Lender shall have made any demand under this Agreement and
although such obligations may be unmatured. The rights of each Lender under this
Section are in addition to other rights and remedies (including other rights of
setoff) which such Lender may have.

                  SECTION 9.09. GOVERNING LAW; JURISDICTION; CONSENT TO SERVICE
OF PROCESS. (a) THIS AGREEMENT SHALL BE CONSTRUED IN ACCORDANCE WITH AND
GOVERNED BY THE LAW OF THE STATE OF NEW YORK.

                  (b) Each of the parties hereto hereby irrevocably and
unconditionally submits, for itself and its property, to the nonexclusive
jurisdiction of the Supreme Court of the State of New York sitting in New York
County and of the United States District Court of the Southern District of New
York, and any appellate court from any thereof, in any action or proceeding
arising out of or relating to any Loan Document, or for recognition or
enforcement of any judgment, and each of the parties hereto hereby irrevocably
and unconditionally agrees that all claims in respect of any such action or
proceeding may be heard and determined in such New York State or, to the extent
permitted by law, in such Federal court. To the extent permitted by law, each of
the parties hereto agrees that a final judgment in any such action or proceeding
shall be conclusive and may be enforced in other jurisdictions by suit on the
judgment or in any other manner provided by law. Nothing in this Agreement or
any other Loan Document shall affect any right that either Agent or any Lender
may otherwise have to bring any action or proceeding relating to this Agreement
or any other Loan Document against Holdings or the Borrower or its properties in
the courts of any jurisdiction.

                  (c) Each of the parties hereto hereby irrevocably and
unconditionally waives, to the fullest extent it may legally and effectively do
so, any objection which it may now or hereafter have to the laying of venue of
any suit, action or proceeding arising out of or relating to this Agreement or
any other Loan Document in any court referred to in the first sentence of
paragraph (b) of this Section. Each of the parties hereto hereby irrevocably
waives, to the fullest extent permitted by law, the defense of an


                                       45
<PAGE>

inconvenient forum to the maintenance of such action or proceeding in any such
court.

                  (d) Each party to this Agreement irrevocably consents to
service of process in the manner provided for notices in Section 9.01. Each of
Holdings and the Borrower hereby irrevocably designates, appoints and empowers
CT Corporation System, with offices on the date hereof at 111 Eighth Avenue,
13th Floor, New York, New York 10011, as its designee, appointee and agent to
receive and accept for and on its behalf, and in respect of its property,
service of any and all legal process, summons, notices and documents which may
be served in any action or proceeding described in paragraph (b) above. If for
any reason such designee, appointee and agent shall cease to act as such, each
of Holdings and the Borrower agrees to designate a new designee, appointee and
agent in New York City on the terms and for the purposes of this provision
reasonably satisfactory to the Administrative Agent. Nothing in this Agreement
or any other Loan Document will affect the right of any party to this Agreement
to serve process in any other manner permitted by law.

                  SECTION 9.10. WAIVERS. (A) WAIVER OF JURY TRIAL. EACH PARTY
HERETO HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY
RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR
INDIRECTLY ARISING OUT OF OR IN CONNECTION WITH THIS AGREEMENT, ANY OF THE OTHER
SUPPORT DOCUMENTS OR ANY SECURED INSTRUMENT. EACH PARTY HERETO (A) CERTIFIES
THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED,
EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF
LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT
AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT, ANY
OF THE OTHER SUPPORT DOCUMENTS OR ANY SECURED INSTRUMENT, AS APPLICABLE, BY,
AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 9.10.

                  (B) WAIVER OF SOVEREIGN IMMUNITY. TO THE EXTENT THAT ANY PARTY
HERETO HAS OR HEREAFTER MAY ACQUIRE ANY IMMUNITY FROM JURISDICTION OF ANY COURT
OR FROM ANY LEGAL PROCESS, SUCH PARTY HEREBY WAIVES SUCH IMMUNITY AND AGREES NOT
TO ASSERT, BY WAY OF MOTION, AS A DEFENSE, OR OTHERWISE, IN ANY SUCH SUIT,
ACTION OR PROCEEDING, ANY CLAIM THAT IT IS NOT PERSONALLY SUBJECT TO THE
JURISDICTION OF THE COURTS NAMED IN SECTION 9.09(B), THAT IT IS IMMUNE FROM ANY
LEGAL PROCESS (WHETHER THROUGH SERVICE OR NOTICE, ATTACHMENT PRIOR TO JUDGMENT,
ATTACHMENT IN AID OF EXECUTION, EXECUTION OR OTHERWISE) WITH RESPECT TO ITSELF
OR ITS PROPERTY, OR ATTACHMENT EITHER PRIOR TO JUDGMENT OR IN AID OF EXECUTION,




                                       46
<PAGE>

BY REASON OF SOVEREIGN IMMUNITY, OR OTHERWISE, THAT THE VENUE OF THE SUIT,
ACTION OR PROCEEDING IS IMPROPER OR THAT THIS AGREEMENT OR ANY OTHER SUPPORT
DOCUMENT OR THE SUBJECT MATTER HEREOF OR THEREOF MAY NOT BE ENFORCED IN OR BY
SUCH COURTS.

                  SECTION 9.11. HEADINGS. Article and Section headings and the
Table of Contents used herein are for convenience of reference only, are not
part of this Agreement and shall not affect the construction of, or be taken
into consideration in interpreting, this Agreement.

                  SECTION 9.12. CONFIDENTIALITY. Each of the Agents and the
Lenders agrees to maintain the confidentiality of the Information (as defined
below), except that Information may be disclosed (a) to its and its Affiliates'
directors, officers, employees and agents, including accountants, legal counsel
and other advisors (it being understood that the Persons to whom such disclosure
is made will be informed of the confidential nature of such Information and
instructed to keep such Information confidential), (b) to the extent requested
by any regulatory authority, (c) to the extent required by applicable laws or
regulations or by any subpoena or similar legal process, (d) to any other party
to this Agreement or any other Participating Credit Agreement, (e) in connection
with the exercise of any remedies hereunder or any suit, action or proceeding
relating to this Agreement or any other Loan Document or the enforcement of
rights hereunder or thereunder, (f) subject to a written agreement containing
provisions substantially the same as those of this Section, to any assignee of
or Participant in, or any prospective assignee of or Participant in, any of its
rights or obligations under this Agreement, (g) with the consent of Holdings or
the Borrower or (h) to the extent such Information (i) becomes publicly
available other than as a result of a breach of this Section or Section 8.12 of
the Common Agreement or (ii) becomes available to either Agent or any Lender on
a nonconfidential basis from a source other than Holdings or the Borrower. For
the purposes of this Section, "INFORMATION" means all information received from
Holdings or the Borrower relating to Holdings or the Borrower or its business,
other than any such information that is publicly available or available to
either Agent or any Lender on a nonconfidential basis prior to disclosure by
Holdings or the Borrower. Any Person required to maintain the confidentiality of
Information as provided in this Section shall be considered to have complied
with its obligation to do so if such Person has exercised the same degree of
care to maintain the confidentiality of such Information as such Person would
accord to its own confidential information.

                  SECTION 9.13. INTEREST RATE LIMITATION. Notwithstanding
anything herein to the contrary, if at any time the interest rate applicable to
any Loan, together with all fees, charges and other amounts which are treated as
interest on such Loan under applicable law (collectively, the "CHARGES"), shall
exceed the maximum lawful rate (the "MAXIMUM RATE") which may be contracted for,
charged, taken, received or reserved by the Lender holding such Loan in
accordance with applicable law, the rate of interest payable in respect of such
Loan hereunder, together with all Charges payable in respect thereof, shall be
limited to the Maximum Rate and, to the extent lawful, the interest and Charges
that would have been payable in respect of such Loan but were not payable as a
result of the operation of this Section shall be cumulated and the interest and
Charges payable to such Lender in respect of other Loans or periods shall be
increased (but not above the Maximum Rate therefor) until such cumulated amount,
together with interest thereon at the Federal Funds Effective Rate to the date
of repayment, shall have been received by such Lender.

                  SECTION 9.14. JUDGMENT CURRENCY. (a) The Borrower's
obligations hereunder and each of the Borrower's and the other Loan Parties'
obligations under the other Loan Documents to make payments in Dollars (the
"OBLIGATION CURRENCY") shall not be discharged or satisfied by any tender or
recovery pursuant to any judgment expressed in or converted into any currency
other than the Obligation Currency, except to the extent that such tender or
recovery results in the effective receipt by the Administrative Agent, the
Collateral Agent or a Lender of the full amount of the Obligation Currency
expressed to be payable to the Administrative Agent, the Collateral Agent or
such Lender under this Agreement or the other Loan Documents. If, for the
purpose of obtaining or enforcing judgment against the Borrower or any other
Loan Party in any court or in any jurisdiction, it becomes necessary to convert
into or from any currency other than the Obligation Currency (such other
currency being hereinafter referred to as the "JUDGMENT CURRENCY") an amount due
in the Obligation Currency, the conversion shall be made, at the rate of
exchange at which such Judgment Currency can be converted into the Obligation
Currency (as quoted on the applicable Reuters World Spot Page) determined, in
each case, as of 11:00 a.m., New York City time, on the date immediately
preceding the day on which the judgment is given (such Business Day being
hereinafter referred to as the "JUDGMENT CURRENCY CONVERSION DATE").

                  (b)  If there is a change in the rate of exchange
prevailing between the Judgment Currency Conversion Date and


                                       48
<PAGE>

the date of actual payment of the amount due, the Borrower covenants and agrees
to pay, or cause to be paid, such additional amounts, if any (but in any event
not a lesser amount), as may be necessary to ensure that the amount paid in the
Judgment Currency, when converted at the rate of exchange prevailing on the date
of payment, will produce the amount of the Obligation Currency that could have
been purchased with the amount of Judgment Currency stipulated in the judgment
or judicial award at the rate of exchange prevailing on the Judgment Currency
Conversion Date.

                  (c) For purposes of determining the rate of exchange for this
Section, such amounts shall include any premium and costs payable in connection
with the purchase of the Obligation Currency.

                  SECTION 9.15. AMENDMENT AND RESTATEMENT. This Agreement was
